Description Model 16591 is an UV/IR2 flame detector designed for use where open flaming fires may be expected and responds to the light emitted from flames during combustion. The UV/IR2 flame detector is designed to protect areas where open fires may be expected and detects most flames from hydrocarbon fires with 4.3μm emissions through to invisible fires such as hydrogen. The UV/IR2 Flame Detector is sensitive to flickering, low frequency (1-15Hz) infrared radiation along with ultra-violet emitted by flames during combustion. This detector has a UV sensor and two IR sensors which respond to different wavelengths of both the ultra-violet and the infra-red spectrum. The signals from these sensors are processed by the detector and checked for characteristics of a flame. The simultaneous detection of both the UV and the IR light by the sensors will signal an alarm. False alarms from flickering sunlight, arc welding and lighting are eliminated by a combination of UV and dual IR signal processing techniques. The UV/IR2 flame detector has selectable output options or relay contacts or 4 to 20mA signal as standard.
